Alkali-labile precursors of dimethyl sulfide in marine benthic cyanobacteria
By the method of cold alkali hydrolysis, 29 marine benthic cyanobacteria were screened for production of alkali-labile precursors of dimethyl sulfide (DMS) including dimethylsulfoniopropionate (DMSP), a compound of significant importance in marine environments. Concentrations of DMS precursors ranged from undetectable to 0.8 mmol (g Chl a)-1. The data correspond to some previous investigations concerning DMSP content of marine cyanobacteria and suggest that marine benthic cyanobacteria are only minor producers of DMSP.
